Can you plz solve for x

Polygon mnopq is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image m′n′o′p′q′. the coordinates of point m are (2, 4), and the coordinates of point n are (3, 5). the slope of is .

The parabola opens: y=√x-4 (principal square root) up down right left

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
